This paper compares the temperature response of magnetic oil to that of conventional nonmagnetic lubricant oil, in an application of electromagnetic induction heating principles to the design of a system suitable for radiant floor heating. Results of experiments carried out using a closed loop system in which a pump circulates oil from a tank through a heat exchanger are presented. Magnetic oil is found to make a small but nontrivial contribution to the energy efficiency of the system.
